Joyce Mitchell Arrested in New York Prison Escape Case

(DANNEMORA, N.Y.) — The female prison worker who was being investigated for her alleged role in the escape of two convicted murders from an upstate prison was arrested Friday, police said.

Mitchell worked in the tailor shop of Clinton Correctional Facility and has spoken with investigators repeatedly since David Sweat and Richard Matt escaped early Saturday June 6.

Investigators have determined that Mitchell did not give the convicted murderers the power tools that they are believed to have used to break out of the maximum security prison, according to Clinton County District Attorney Andrew Wylie.

“She brought contraband into the facility but I’m not going to get into what it was,” Wylie said during a press briefing Friday morning.

Her level of cooperation with the authorities has grown over time, Wylie said.

Two sources confirmed to ABC News on Thursday that corrections officials had previously investigated whether Mitchell had a relationship with Sweat in the year before his escape, but ultimately there was not enough evidence to take any action against Mitchell.
